ATTORNEY United States Patent 3,137,429 MULTIPLE RAILWAY TGGL MACHINE Robert L. Fox, 512 Hilltop Terrace, Aie'xandria, Va. Filed June 28, 1960, Ser. No. 39,255 13 Claims. (Cl. 29-564) This invention relates to railway maintenance and railway equipment and more particularly to a machine for cutting and drilling holes in track rail of different size and weight.

As is well known to railroad maintenance men familiar with the problem of making joints in track rails at desired locations, it if oftentimes necessary to employ two or three machines as well as a large maintenance crew in order to make necessary track joints by cutting, drilling and then uniting the sections together.

In the new method of laying continuous track there has developed a need for a multiple tool machine which can be used to perform the operation of cutting a rail at a desired location for a joint and to then bore six holes, three in each of the two adjacent sections, for the purpose of accommodating the joint bars used to unite the two sections together bythe insertion of bolts through mating holes in the track rail and the joint bar.

As is readily understood there is a need in railroad maintenance of a multiple tool machine which can perform the job of cutting rails to provide desired joints and then to drill three holes in each of the adjacent cut sections so that the track may be quickly and cheaply united together by means of joint bars.

My invention has been made with the foregoing considerations in mind and have many import-ant objectives in its creation and use.

An important object of my invention is provision of a multiple railway tool machine which can be self propelled along a railway track to a desired location for the purpose of quickly, easily and economically cutting rail with a minimum of labor and men and to unite the rail for use by trains thereover.

Another important object of my invention is the provision of a power operated gang of drills in cooperation with a power operated saw for the purpose of cutting track rail to make a joint and to then accurately and exactly drill the necessary holes required to mate with standard joint plates for connecting the rail sections together.

Another important object of my invention is the provision of a multiple tool machine which is advantageously moved along a railway track by its own power on a wheeled frame, and which carries its own power to perform the necessary work operations.

Another and further important object of my invention is the provision of a multiple tool machine which can be used to saw rail and drill desired size holes in track rail of any size and weight, at the proper spacing required.

Another and further important object of my invention is to provide a multiple tool machine with drills that are exactly and accurately positioned on rail sections in a desired arrangement.

Other features and advantages not specifically enumerated will become apparent after a consideration of the following descriptions and the appended claims.

The main frame Reference is again made to FIGURE 1 wherein is shown a 4 wheeled, self propelled vehicle 20 arranged to travel on a railroad track 21 by means of Wheels W. The vehicle is powered by a conventional motor and transmission mechanism (not shown). An operators seat 23 revolvably' mounted to be adjusted about 360 is provided on the front end of the main frame 24. The main frame 24 is formed with longitudinally extending hollow beam members 25 connected at the front and by a plate 26 on which the motor housing 22, is rigidly attached. The box beams 25, intermediate their ends, are bent upwardly to provide substantially upright front portions 13 and the upright rear portion 14. The lower horizontal portions 11 and 12 of the beams 25 are utilized to provide the base of the main frame. The upright portions 13 and 14 carry an upper horizontal portion 15. Thus, intermediate the ends of the main frame an upright supporting structure is provided for carrying the drill and clamp carriage of my invention. Triangular plates 16 are connected at the bends between the upright portions 13 and I4 and the upper horizontal portion 15 of the beam to provide a rigid structure. Transversely extending channel members 27 are connected to the beam at spaced intervals to form a rigid and unitary main frame. Four transverse angle members 28 with their short leg 29 rigidly connected to the under side of portions 15 of the beams 25 are provided to carry 'the drill and clamp carriage 30 as is clearly shown in FIGURES 7 and 8.

Drill and clamp carriage Rigidly attached to the longer leg of the angle members 28 are two inwardly faced channel members 31, whose Web portions 32 are each vertically aligned with and rigidly attached to the inner face of the longer leg of the angle member 28 and whose legs 33 are inwardly positioned to provide trackways for the rollers 34 and 35 of the drill and clamp carriage 30.

The drill and clamp carriage 30 is formed of plates 36, 36 rigidly connected and spaced apart by tube members 37 and 38. Upper tube members 37 are shown to be larger in diameter than the lower tube member 38 as is Patented time s, 1965" seen clearly in FIGURE 8. The tube members extend through the plates 36 and each are provided with reduced outer shafts on which upper rollers 34 and lower roll 35 are mounted. The rollers 34 are mounted on the outer shafts of upper tube member 37 and the rollers 35 are mounted on the outer shafts of lower tube members 38.

As is clearly shown in FIGURES 7 and 8 the carriage 30 is mounted on the channel members 31 such that the lower leg 33 of each channel member forms a trackway at its inner upper surface for the small rollers 35 and the upper leg 33 of each channel member forms a trackway at its outer upper surface for the large rollers 34. Each roller is mounted for rapid detachment on their respective shafts by means of spring clips 40.

Connecting one end of the channel members 31 is a spacing plate 165 which is attached to the channel members by means of bolts 151. Mounted on the outside of the plate 150 by means of bolts 152 in a motor 153. Extending from the motor 153 is a drive shaft 154 on whose outer end is mounted a pulley 155 for rotation therewith. Connecting the opposite ends of the channel members 31 is a plate 156 provided with upstanding ears 157 which are rigidly connected to the Webb section of the channel members by means of bolts 158.

Depending from and rigidly fixed to the plate 156 in alignment with shaft 154 is a stub shaft 159 on which is rotatably mounted a pulley 160. A drive belt or chain 161 is connected between the motor pulley 155 and the pulley 160 for transversely moving the drill and clamp carriage into position over either one of the railway track rails on which the main frame is travelling. The belt or chain 161 is connected by means of lugs 162, mounted on the underside of the carriage plate 39, to effect positive movement of the drill and clamp carriage transversely from track rail to track rail. Stops 163 are mounted by bolts 164 on each end of the channel members for limiting movement of the drill and clamp carriage.

Depending from the carriage 30 and carried by spaced straps 280 which are rigidly attached thereto is an hydraulic cylinder 41. The straps 280 are connected to and carried by the carriage by means of bolts 43. A ram 42 extends from the hydraulic cylinder and carries an integral clevis 44.

Integrally formed with and extending laterally outwardly from the plates 36 is the carriage plate 39. At each outer end the carriage plate 39 is provided with an opening for receiving slidably therethrough vertical fixed shafts 45, 45. Fixedly mounted on the top face of the carriage plate 39 in cooperation with the openings therein are collars 46.

Shafts 45 are formed, at their lower end, with a flat collar like base 47 which is fixedly mounted as by welding to a horizontal member 48. Members 48 at their inner portions are each formed with a vertical leg 49, at right angles thereto, which is received Within and connected to the clevis 44 by means of the machine bolt 50 and nut 51. Depending downwardly and carried by the clevis 44 between the legs 49 is the vertical member 51, as is clearly seen in FIGURE 8; the legs 49 and the vertical member 52 received therebetween are connected to the clevis as one unit by the bolt 50 and nut 51.

In the arrangement shown, the shafts 45 are free to rise and be lowered with respect to plate 39 by means of the extension or retraction of the hydraulic ram 42. In this operation the shafts 45 are free to slide through the holes and collars provided with the carriage plate 39.

The vertical member 52 is formed of an elongated flat plate which provides the central or carrying member for the entire drill and rail clamp assembly.

As seen in FIGURES 3, 4, and 6, plate 52 carries a main shaft 53, each end of which is threaded at 54 to receive an inner nut 55 and an outer nut 56. Mounted on each end of shaft 53 between nuts 55 and 56 is the upper end of a connecting plate 57. The lower end of each connecting plate 57 is mounted on the adjacent outer end of a pivot shaft 58. The outer ends of shaft 58 are externally threaded as at 59 to receive nuts 60 and 61. As seen in FIGURES 3 and 5 the connecting plate 57 is mounted between the nuts 60 and 61 on shaft 58. Shaft 58 is also extended through a hole provided through the lower end of the vertical member 52 and is also carried thereby. In each plate 57 an elongated slot 62 is provided for a purpose to be described hereinafter.

At the central portion of the vertical plate member 52, on each side thereof, a plate 63 is attached as by welding. Each plate 63 is shown to be the same Width as the vertical members 52 and is bevelled at its ends 64. An elongated slot 65 is provided in the vertical plate 52 and an aligned slot 66 is provided in each of the plates 63. As shown in FIGURES 3 and 5, the slots 62, 65 and 66 are aligned with each other.

Connected to and extending upwardly from the shaft 58 intermediate each connecting plate 57 and the vertical plate 52 is an hydraulic cylinder 67. The hydraulic cylinders 67, 67 are mounted on the shaft 58 by means of a T-shaped connector 69. As seen in FIGURES 5 and 6 the connector 69 is provided with a central hole by which it is connected to shaft 58, with the central leg 70 extending upwardly therefrom and being rigidly connected to the housing of the hydraulic cylinder 67. The outer ears 71 of the connector 69 are each provided with an opening 72 for a purpose to be described later.

Ram 68 extends upwardly from the cylinder 67 and carries a rod 73 at its upper end by means of a collar 74 rigidly attached to and forming a part of the ram 68. The rod 73 extends through the collar 74 on each side and is received within the associated slot 62 of plate 57 at one end 75 and within the associated slots 66 and 65 at its other end 76. The ends 75 and 76 of the rod 73 are externally threaded to receive a nut 77. As shown in FIGURES 5 and 6, nuts 77 are threaded on the rod 73 in position to ride against the inner sides of the associated plates 63 and 57. Each nut 77 is of suificient size to extend beyond the width of the slots.

Pivotally mounted at its upper arms 78 and 79 to the bar 73 and at its lower arms 80 and 81 to the shaft 58 is a lazy tong assembly. As seen in FIGURES 5 and 6, the lower arm 81 of the lazy tong assembly carries a thrust member 82 and the arm 80 carries a thrust member 83. The thrust members 82 and 83 have, as seen in FIGURE 6 horizontal L shaped clamps 84 and 85 respectively.

Gripping templets 86 are attached to the clamps 84 and 35 by means of machine bolts or other like fastening means 87. Formed in each templet 86 are drill holes 88. As seen in FIGURE 5, each templet is provided with 3 drill holes; it being obvious, however, that any desired number of drill holes may be provided in each templet.

Drill assembly Referring to FIGURES 3 and 4, the drill assembly of my invention is clearly shown. Therein I have provided and adjustably mounted on the shaft 53 the collars 90. The collars 90 may be fixed at any point along the shaft 53 by means of a tightening bolt 91 which is provided to connect the upstanding ears 92 of each collar and to thus fixedly mount the collars on the shaft 53.

Rigidly connected to and forming an extension of each collar 90 is a U-shaped connecting member 93, the web portion 94 of which is provided with holes by means of which a strap member 95 is connected with machine bolts 96 or the like fastening means. The strap member is formed integrally with and provides an upper connecting strap extension for a substantially rectangular open side box housing 97. The box housing 97 is provided with an upper platform 98, side plates 99 and a base member 160.

Mounted on the upper platform 98 of each box housing by means of machine bolts 101 is an hydraulic motor 102.

The outer housing of motor 102 is provided with ears 103. The ears 103 are provided with holes which are aligned with mating holes in the platform 98 so that bolts 101 extending therethrough and drawn tight, connect the motor rigidly to the platform.

The housing of the motor is provided with a reduced portion 164 housing the shaft bearing 105 through which extends the shaft 106. Mounted on the outer end of each shaft 106 is a pulley wheel 107.

Connected to the underside of the box housing 97, to the base member 101 is a shaft housing 1% provided with an internal shaft bearing 109. Rotatably mounted in the bearing 199 is a shaft 110, the outer end of which is provided with a pulley wheel 111. The inner end of the shaft 110 extends beyond the housing and is provided with a transverse bore therethrough.

As is clearly seen in FIGURE 4, a drill holder 112 formed with a longitudinal bore is received on the inner end of shaft 110. The drill holder is provided on its larger end with transverse holes which mate with the bore in the shaft 110 in its fully seated position. A pin 113 with an enlarged portion on one end may then be extended through the mating holes in the drill holder and the bore in the shaft. A cotter .pin 114 is provided on the opposite end of the pin to hold the parts together in :the assembled position. Thus, the drill holder will rotate with the shaft 110 in its operation.

The reduced end of the drill holder is split (not shown) at diametrically opposite sides in a longitudinal direction and is provided with external threads. The reduced end of the drill holder provides a chuck for holding a drill 115 which is received within the longitudinal bore for rotation therewith. The drill locking member 116 is formed with a central bore 117 and is internally threaded for engagement on the threaded portion of the drill holder. As is obvious, the locking member 116 is threaded onto the drill holder 112 for locking the drill in the drill holder for rotation therewith during the work operation. A double chain drive 118 is shown connected between the motor pulley 107 and the drill pulley 111 for operating the drill.

A rod 119 is provided in each box housing 97 and is held in position by nuts threaded on the outer ends of the rod and tightened up to the outer faces of the side plates 99. An hydraulic cylinder 120 with a housing provided on one end with a U-shaped connecting clevis 121 is attached to the connecting member 69 by means of a pin 125 inserted through holes in each ear of the U-shaped clevis and extending through the opening 72 of the ear 71. The pin is held in position by means of spring clips or any other well know fastening means.

Extending from the housing of the hydraulic cylinder 120 at the end opposite to the clevis is a ram 122. The outer end of the ram 122 is provided with a ring 123 which is connected to the box housing by means of the rod 119 which is received therethrough.

As appears obvious, the drills of my invention are operated by means of the hydraulic motor 192. The drill being rotated through the double chain drive provided between the pulleys 107 and 111. The entire drill assembly is then brought into engagement in the work operation of drilling a hole in the rail 21 by means of the hydraulic cylinders 120. The extension of the rams 122 from the cylinder disengages the drill from its operation by pivoting the box housing strap 95 about shaft 53. The contraction of the ram 120 within the cylinder places the drill in position for drilling a hole in the rail so that further contrac tion of the ram 122 while the drills are in operation will cause the drills to bore holes in the rail 21 as they rotate. As is further shown in FIGURE 4, the drills are mounted to bore three holes on each side of the rails.

Saw assembly Referring to FIGURES 2 and 9 through 15, wherein the saw assembly of any invention is shown, supports 130 6 extend rearwardly from the upright portions 14 of the main frame to support an upright saw transfer rack 131. The

transfer rack comprises end plate members 132 rigidlyconnected together at the bottom thereof by a plate 133. Plate 133 is connected to the rear base members 12 of the frame 24. Mounted in the end plate members 132 in aligned holes provided therein are tubular members 134. The tubular members are threaded on their outer ends 135. Nuts 136 and 137 are provided for fixedly attaching the tubular members 134 with respect to the plates 132. Nuts 136 are mounted so as to abut the inner face of the plates 132 and nuts 137 are then tightened against the outer face of the plates. The supports are rigidly connected to alternate tubular members as by welding.

A saw carriage consisting of a plate 140 provided with spaced depending legs 141 is mounted for transverse travel along the tubular members 134. Rigidly connected to the plate 140 at selected locations are forwardly extending angle brackets 142, at the outer forward end of each of which is rigidly connected, as by welding, a U-shaped bracket 143. Mounted within the U-shaped bracket 143 by means of a removable shaft 144 is a rotatable spool 145.

Rigidly connected to the plate 140, below each bracket 142, are spaced angle brackets 146 and 147 between which are mounted removable shafts 148 and 149. Spools 150 are rotatably mounted on each shaft 148 and 149. As is seen clearly in FIGURES 9 and 11, the carriage is mounted for transverse movement over the rack 131, the spools 145 designed to travel over the tops of alternate tubular members 134 and the spools 1S0 designed to embrace and travel along the sides of the intermediate ones of such tubular members.

Mounted on the outer face of one of the end plate members of the rack 131 is an hydraulic cylinder 166. Extending upwardly from the cylinder 166 is a drive shaft 167 on which is fixedly mounted a pulley 168 for rotation therewith. Mounted on the outer face of the other end plate member of the rack 131 is an angle support 169 on the upper face of which is fixedly mounted a stub shaft 170. Rotatably mounted on the shaft 170 is a pulley 171. A drive belt or chain 172 is connected between the drive pulley 168 and the pulley 171 for transversely moving the saw carriage from one side to the other of the transfer rack, to thus position the saw assembly over the track rail which is to be cut. A lug 173 is attached to the upper face of the uppermost bracket 142 and the belt or chain 172 is connected thereto to effectively move the saw carriage transversely to a position over a railway track. Obviously the transverse movement of the saw carriage is limited by the end plate membes 132.

Extending in a rearward direction and rigidly connected to the rear face of plate 140, centrally thereof, is a supporting arm 175 having a reduced end 176 in which a hole 1s provided. Also rigidly attached to the rear face of the plate 141 above the leg portions 141 of the plate 140 are spaced angle inons 177. The shorter leg 179 of the angle iron 177 is attached to the plate 140 as by welding or the like. The longer leg 18% of the angle iron extends outwardly at right angles to the plate 140. The legs 141 of the plate 140 are bent in a rearward direction as seen 1n FIGURE 9 and form a beveled foot member 181.. A post 182. is rigidly connected between each angle iron 177 and the associated foot member 181.

Mounted for vertical adjustment on the posts 182 is the carriage sub frame 190. The sub frame comprises a vertical plate 183 to which is welded the forwardly extending spaced arms 184 and 185. Four pairs of spaced arms are provided as will be obvious from FIGURES 9, 11 and 12.

Metal spools 186 are journaled in the arms 184 and 185 in position to embrace and ride on the post 182 in a vertical direction. As is clearly seen in FIGURE 9, each pair of arms is provided with two spools 186, and two pairs of arms with spools are mounted to ride on each post 182.

Extending rearwardly from and positioned centrally adjacent the upper portion of the plate 183 is a vertically extending supporting member 188 provided with a bored hole which is aligned in a vertical direction with the supporting arm 176. The holes in the supporting arm 176 and the supporting member 188 are aligned in a vertical direction. Detachably connected to the supporting arm 176 by means of a pin 191 extending through the hole provided therein is a clevis 192 which is rigidly attached to and forms a part of one end of the housing of the hydraulic cylinder 193. Extending from the opposite end of the hydraulic cylinder 193 is a ram 194 which is provided at its outer end with an enlarged head forming a clevis 195. The clevis 195 is detachably attached to the supporting member 188 by a pin 196 extending through openings provided in the clevis and in the supporting member. Spring clips 197 are provided for retaining the pins 191 and 196 in the assembled position. Detachably attached to the lower part of the rear face of the plate 183 by means of upper and lower bolts 200 and nuts 201 is a housing 202. The housing is generally triangular in shape, as seen in FIGURE 9, and consists of the upright portion 203, which is secured to the plate 183 by the bolts 200, the base or horizontal portion 204 and the connecting leg portion 205. Attached by means of the upper bolts to the plate 183 and the housing 202 is a saw support plate 206. The saw support plate is also at tached to the upper end of the connecting leg portion 205 by means of bolts 207. From its connection to the connecting leg portion, the saw support extends horizontally rearwardly and is provided with spaced legs 208, as shown in FIGURES 2 and 9, bent downwardly in spaced parallel position with respect to the connecting leg portion 205.

A pair of Water tank support straps having a horizontal leg 209 are connected to the horizontal portion of the saw support by means of bolts 210. The tank support straps are bent at 211 to form depending vertical legs 212; the ends of the legs 212 are each provided with a saw guide 213. A triangular stiffening plate 214 is connected between the legs 209 and 212 to brace and strengthen the structure.

Mounted on the underside of the connecting leg portion 205 by means of bolts 216 is a conventional hydraulic cylinder 215. Extending from the cylinder 215 is the drive shaft 216 on which is mounted a bevel gear 217 for rotation therewith. Meshing with the bevel gear 217 is a bevel gear 218 carried by-a driven shaft 219 extending through a bearing 220 rigidly connected between the leg portion 205 and one of the saw support legs 208. The driven shaft 219 extends through the leg portion and the saw support leg and its upper end is provided with a saw pulley 221. Mounted on the other saw support leg is a stub shaft 222 on which is rotatably mounted the saw pulley 223.

As is believed to be clearly shown in FIGURE 9, the hydraulic motor 215, through drive shaft 216 rotates the gear 217 which in turn drives the gear 218. Rotation of the driven shaft 219 by means of gear 218 attached thereto is thus effected to rotate the saw pulley 221. Rotation of the saw pulley 221 thus drives the chain saw 225, which is rotated thereby.

The chain saw passes through the saw guides 213 provided on the ends of the legs 212. Each guide 213 is positioned on a side of the track rail opposite that of the other saw guide in the operative position of the saw. The saw pulleys are here shown to be positioned at an angle of approximately 45 to the vertical, as seen in FIGURE 9, in the arrangement of my device and the saw in passing through the saw guides is turned by the guides to provide a vertical perpendicular alignment to its operation in sawing a rail in two pieces. It is to be noted, however, that the precise angle of position of the saw pulleys is not critical and that variances in angular position may be made without departing from the intent of the invention here disclosed.

Each saw guide 213, as seen in FIGURES 14 and 15 is formed by a pair of angle members. Each angle member has an upper vertical portion 227 rigidly attached, as by welding, to the leg member 212. The horizontal plate portion 228 of the angle member extends laterally outwardly and at right angles to the leg 212.

A plate 231 is carried in spaced relation to and by the horizontal plate portion 228 of the angle member by means of the straps 232 and 233 welded to plate 231 and portion 228. Rollers 235 are provided between each plate 228 and 231 to freely rotate about a fixed shaft 234 attached to the plates.

A shaft 229 is removably mounted between the vertical portions 227 of the angle members forming the saw guide 213. Mounted for free rotation on shaft 229 is a guide roller 230. As is clearly seen from FIGURES 10, 14 and 15, the band saw is thus additionally guided in its movement through the guides 213 by the rollers 230. The saw 225 is thus trained to pass between the rollers 235 and under the roller 230 provided in the saw guides 213 to properly lead the saw during the working movement.

As shown in FIGURES 1, 2 and 9, a water tank 250 is mounted on a plate 252 which is connected to the horizontal legs 209 of the tank support straps by means of the machine bolts 254. By any conventional means, such as rubber line (not shown), the water which has been stored in the tank 250 is applied to the saw blade during the sawing operation in order to avoid excessive frictional heating of the blade and to cool the blade.

Hydraulic system FIGURE 16 diagrammatically shows the hydraulic system used in the operation of my device. Although I have here shown and preferably utilized an hydraulic system, this system is conventional and by itself forms no part of my invention. Obviously it would be entirely possible to operate my invention by the use of air motors or electric motors, except for the greater efficiency and greater power obtained in my use of an hydraulic system.

In FIGURE 16 I have shown manual control valves for the operation of the motors used in my invention. Control valve 240 is used to operate the motor 153 which is used to move the drill and clamp assembly transversely of the railway track. Control valve 241 operates the cylinders 67, 67 to bring the clamp engagement members, and the templates carried thereby, into engagement with the track rail. Control valve 242 operates the cylinder 41 which is used to raise and lower the drill and clamp assembly into and out of its working level. The control valve 243 is used to operate the cylinders when it is desired to bring the drills into their position of drilling holes in the track rail or to take the drills out of such position. The control valve 244 is used to operate the motors 102 and thus operate the drills so as to bore holes in the track rail after the drills have been moved into position by the control valve 243. The control valve 245 operates the cylinder 166 in order to transversely shift the saw assembly over one or the other of the track rails upon which the main frame is travelling. The control valve 246 is used to operate the cylinder 193 for raising and lowering the band saw during the work operation. The control valve 247 is used to activate the cylinder 215 and to thus operate the band saw when it is desired to saw a rail in two.

Operation In the operation of the machine of my invention, the main frame under its own power is brought over the railway track 21 to the job site. The operator, after locating the desired point at which the rail is to be cut, then operates the control valve 245 to move the saw assembly along the tubular members 134 of the transfer rack 131 to a position over the track rail which is to be cut. The cylinder 215 is activated by the control 247 to oper ate the band saw 225. While the saw is in operation the operator then operates the control 246 to activate the lift cylinder 193 and thus cut into the track rail. During the operation of the saw, water from the tank 250 is applied to cool off the saw blade.

It.is to be noted here that my invention utilizes a band saw for the cutting of a railway track, however, it is within the scope of my invention to utilize a circle saw blade in place of the band saw with but a simple modification of the structure shown.

After the track rail has been cut by my machine, the operator raises the saw and its framework out of engagement by operation of the valves 245 and 246 and by means of the valve 247 stops the saw. He then propels the machine rearwardly to a point wherein the drill and clamp assembly will be properly positioned over the newly cut rail.

The operator then operates the control valve 24%) to activate the motor 153 and to move the drill and clamp assembly over the desired track rail. The lift cylinder 41 is then activated by the control valve 242to lower the drill and clamp assembly and to adjust them into proper working position. The clamp engagement cylinders 67 are then activated to bring the templates 86 into engagement with the rail; a pair of templates are thus posi-' tioned on each side of the cut made in the rail.

As is believed obvious, different templates are utilized depending on the weight and size of the track rail since difierent size track rail require a different size template. In my invention the different size templates are applied by first removing the bolts 87 and then fastening a desired template to the clamps 84 and 85 by the replacement and tightening up of the bolts. Because of different size templates as is seen in FIGURE 5, the lazy tong members may be adjusted along the rods 73 and shaft 58 and fixed in position therealong by means of the pins 282 to compensate for differences in location of drill holes in the different templates.

After the clamp and templates have been positioned, the operator activates the cylinders 102 to operate the drills and while thus operatingthe drills he operates the control valve 243 to activate the cylinders 120 and by retraction of the rams 122 move the drills into position to drill holes in the track rail; the drills passing through the drill holes in the template.

It is to be further noted at this point that the drill assembly members are adjustable along the shaft 53 in order to properly align the drills with the template drill holes. Also, as is believed obvious, it would be but a simple mechanical expedient to remove any or all of the drills and their assembly from the shaft 53 or to deactiva-te any of the drills if so desired.

When the holes required in the track rail have been drilled, the cylinders 120 are activated to take the drills out of the working position; control valve 244 is used to stop the drills; the cylinders 67 are activated to remove the clamp engagement of the template; and the cylinder 41 is activated to raise the entire drill and clamp assembly upwardly out of engagement with the rail. The entire machine is then ready to be moved to another location where desired or the cylinder 153 may be activated to move the entire drill and clamp assembly to the opposite rail.

Numerous modifications and variations of the present invent-ion will occur to those skilled in the art after a careful study of the invention which I have disclosed. For example, it is believed obvious that the operator of my device could reverse the procedure of working on the track rail by first drilling the holes in the track rail and then to saw therail in two. All such modifications and variations which come .within the spirit and scope of the present invention are intended to be included herein as fully and completely as if they had been specifically illustrated, described and claimed herein.

The embodiment specifically described and claimed here is exemplary only and is not intended to limit the scope of this invention.

The exact construction and relative positioning of the various component parts of this invention is by way of example and may be modified substantially within the scope and spirit of any invention without departing therefrom,
